The Metal Gutter Manufacturers Association was formed in 1994 to represent the leading UK manufacturers of metal gutters. Membership of MGMA is open to all companies who manufacture and market metal gutters, downpipes and their associated fittings in the United Kingdom. In addition, membership is open to those companies who provide a range of professional support services to the metal rainwater systems industry.

The Association seeks to foster and take part in research and all forms of technical development in relation to metal gutters and to encourage the best methods of their production and use with the construction and allied industries.

The Association has produced a Membership Charter to reflect the current concerns of the industry with particular reference to technical ethos, health and safety and environmental issues. In accordance with the Charter, the MGMA will ensure that its members undertake all work in accordance with relevant health and safety legislation and have a health and safety policy which they uphold both in principle and practice.

In addition, members are required to have due regard for environmental issues during procurement, delivery (including installation implementation) and waste disposal and members are committed to minimising adverse environmental impact in the provision of their products and/or services.

The MGMA is the only organisation which represents the major UK manufacturers and is, therefore, a valuable source of
information and advice on all matters relating to metal gutters.
